Surface Coating of Bonded Neodymium Magnet

MPCO can provide epoxy resin electrophoresis, acrylic resin electrophoresis, epoxy resin spraying, Teflon spray, Parry deposition, vacuum soaking and other coating and surface treatment technology to meet the requirements of corrosion resistance, solvent resistance and friction resistance in the long-term and different use environment. Specific coating requirements can be selected and stacked according to the environmental requirements.

Surface Coating of Bonded Neodymium Magnet

Due to the low corrosion resistance of NdFeB magnets, we need to do surface treatment before applications.

The electroplating flows are as follow:

It may take a complete flow and a long time to do chamfering and cleaning, so electroplating needs a period to proceed.
The available coatings are as follows:

The most popular coatings are Zinc plating, Nickel plating, Epoxy and Passivation, the other coatings are Tin plating, Chromium plating, Gold plating, and Ag plating etc.
